I am the Omelet Queen. Listen up:

Mix the eggs thoroughly in a bowl. Put some olive oil in a small skillet, and heat using the medium setting. When the oil is heated, pour eggs in. Pick the skillet up by the handle and rock gently back and forth over the heat. After a minute or even less, use a spatula to lift up the part of the omelet that is set . Allow the uncooked eggs to run underneath the lifted up part, to the bottom of the pan. Continue rocking the pan gently and repeat the lifting etc. until the entire omelet is lightly cooked. Then flip one half of the omelet over the other half. Let this cook until the bottom is very lightly browned. You're done!

If you want to add fillings, do so before the flipping stage. Make sure the filling is prepared (cut to size) BEFORE you start cooking the omelet, because it cooks very quickly.

Enjoy! Some wonderful fillings are mushrooms, spinach and tomato, cream cheese, ricotta cheese, or all of the above.
